Prodisc-L

A concept from the field of joint endoprosthetics

Extensive experience• Developed as a result of decades of experience in knee

and hip prosthetics• Over 15,000 implanted Prodisc-L prostheses since 1990• Polyethylene inlays in conjunction with cobalt-chro-

mium-molybdenum plates have been in clinical use in knee, hip and spinal prosthetics for several decades

Motion preservation• Retention of the physiological range of motion for

flexion/extension, rotation and lateral inclination• Restoration of the height of the relevant segment,

anatomical balance, and the stability of the spinal column

• Guided and controlled motion potentially limits the load on facet joints

Good anatomical fit• The size of the implant, the lordosis angle and the

height of the prosthesis can be interchanged to suit patient anatomy

• Anatomical design of the implant plates

Fixation• Central keels and spikes provide primary fixation• Porous titanium-coated implant plates potentially allow

for osteointegration


Minimally invasive access

The instruments: • Narrow, indicated instruments allow short, mini-

mally invasive surgery and therefore earlier patient mobilization

• Trial implants with adjustable stop to prevent excessive posterior positioning

• The keel bed is prepared while the chisel is guided over the trial implant

• The implant is guided into proper position via the chisel cut

• Orientation at the midline for precise implanting

Indications and Contraindications

Prodisc-L implants are used to replace a lumbar inter-vertebral disc and to restore disc height and segmental motion.

IndicationsLumbar discopathy

Contraindications• Spinal stenosis, radiculopathy• Increased segmental instability• Spinal deformities, spondylolisthesis above 25%• Radiographic confirmation of severe facet joint disease

or degeneration• Osteoporosis, osteochondrosis, and severe osteopenia• Acute or chronic systemic, spinal, or localized

infections• Systemic and metabolic diseases• Any medical and surgical conditions precluding the

potential benefit of spinal surgery• Foreign body sensitivity to the implant materials• Dependency on pharmaceutical drugs, drug abuse,

or alcoholism• Pregnancy• Obesity• Lack of patient cooperation

Patient exclusion recommendationsPatient selection is one of the most important factors contributing to the outcome of the total disc replace-ment procedure. The following may affect clinical out-comes:• A condition of senility or mental illness, alcoholism or

smoking• Dependency on pharmaceutical drugs or drug abuse• The patient’s occupation or activity level• Compromised vertebral bodies at affected level due to

current or past trauma (fractures) • Substantial loss of disc height, where applied segmen-

tal distraction may lead to damage of the great vessels • Involved vertebral endplate dimensionally smaller than

the minimum implant footprint size in both the medial-lateral and the anteriorposterior directions

• Severe abnormality of the endplate (e.g. large Schmorl nodes)

• Posterior spinal defect (e.g. Pars defect)

Kinematics

The kinematics correspond to the physiological condi-tions in the vertebral joints1:

The rotational center is just below the superior endplate of the affected caudal vertebral body. The location of the center of rotation and the flexion radius correspond to the natural joint guidance in the vertebral joints. The physiological range of motion in regard to flexion/exten-sion and lateral bending is restored. The axial rotation is limited only by the anatomical structures and not by the prosthesis. Pure translatory movements are not possible due to the ball and socket principle.

Implants

Two different sizes are available for enhanced coverage of the vertebral endplates:

• M and L

The patient-specific intervertebral disc height and sagit-tal alignment of the affected segment can be restored thanks to:

• three different heights (10, 12 and 14 mm)• four lordosis angles (3°, 6°, 9° and 11°)

Preoperative Planning

Recommendation on the application of the various lordosis angles

If the patient is in an upright position, the PE-inlay should always be placed in as horizontal a position as possible. It is essential to ensure that the PE-inlay is not inclined in a posterior direction.

The following recommendations apply to most cases:

L5/S1Inferior plates with lordosis angles should be selected for L5/S1 if the angle between the horizontal (for upright patients) and the S1 endplates is at least 15°.

Examples: A combination of 3° superior plate and 3° inferior plate for a segmental lordosis of 6°, or a combi-nation of 3° superior plate and 8° inferior plate for a segmental lordosis of 11°.

L4/L5 and higherInferior plates without a lordosis angle (0°) should gener-ally be used for L4/L5 segments and higher.

A prosthesis with a 3° lordosis angle (combination of 3° superior plate and 0° inferior plate) should only be used in segments with a segmental lordosis of close to 0°.

Note: Only implants with a total lordosis angle (3°, 6°, 9° and 11°) represented by a trial implant may be implanted.

Note: In order to reduce the risk of atraumatic peri-prostheic vertebral fractures, surgeons must con-sider all co-morbidities, past and present medica-tions, previous treatments, etc. Upon reviewing all relevant information the surgeon must determine whether a bone density scan is prudent. A screen ing questionnaire, SCORE (Simple Calculated Osteopo-rosis Risk Estimation) may be used to screen pa-tients if a DEXA is performed, exclusion from re-ceiving the device should be considered if the DEXA bone density measured T-score is < –1.0 as this pa-tient may be osteoporotic.


Surgical Technique

1. Approach

Expose the intervertebral disc and the adjacent vertebral bodies through the anterior approach to the lumbar spine. The approach can either be transperitoneal or retro peritoneal. Identify and mark the midline with the image intensifier.

2. Discectomy

Required instrument

SFW580R Elevator

Carefully clean out the intervertebral space with the ele-vator and remove the intervertebral disc tissue and carti-lage fragments from the endplates.


3. Mobilize segment

Required instruments

SFW550R Spreader Forceps, straight

SFW650R Spreader Forceps, curved

Prior to distraction ensure that the position of the spreader forceps posterior is adequately deep. Check the lateral position using the image intensifier.

Distract the intervertebral space with the spreader for-ceps in a parallel manner to restore the height and to enable access to the posterior part.

Note: An essential prerequisite for a satisfactory clinical result is good mobilization. Insufficient mo-bilization can also result in an overload of the inser-tion instruments.

Surgical Technique


4. Insert the trial implant

SFW601R Prodisc-L Stop, adjustable, for Trial Implants

SFW602R Prodisc-L Screwdriver for Adjustable Stop


Determine the final size, height and lordosis angle and the position of the prosthesis. The aim is to select the largest possible footprint with the smallest necessary height.

Align the trial implant with the midline; while monitoring the process on the image intensifier, carefully use the hammer to insert the trial implant into the intervertebral space to the rear edge of the endplate.

The trial implant should be lightly secured by the end-plates of the adjacent vertebral bodies. If the implant is seated too loosely in the intervertebral space, select the next highest size. Check the position of the trial implant using the image intensifier, both from an AP perspective as well as laterally.

Note: The trial implant can be optimally positioned with the aid of the adjustable stop to prevent the im-plant from being inserted too far into the interverte-bral space. If the trial implant must be positioned more deeply, the stop can be adjusted using the screwdriver. One 360° rotation equals 1 mm.


5. Chiseling


SFW867R Prodisc-L Chisel, 10 mm




Guide the chisel over the shaft of the trial implant and create the keel bed for the prosthesis.

The selected trial implant serves as a guide for the chisel and sets the direction and chisel depth.

The chisel cut determines the final implant position and must therefore be checked with the image intensifier.

Precaution: Heterotopic ossification (HO) is a possi-ble cause for fusion of the treated segment. Copious saline lavage is recommended to remove osteogenic stimuli (blood/bone marrow). HO might be reduced when bone wax is used to close cavities in the bone (screw holes) and open bone surfaces after removal of anterior osteophytes¹.

Surgical Technique


6. Insert the implant plates


SFW672R Prodisc-L Inserter for size M

SFW673R Prodisc-L Inserter for size L


Place the top and bottom implant plates on the inserter. Lock the bottom plate by turning the inserter arms. Using the chisel cuts as a guide, insert the implant plates into the intervertebral space.

Check the final position of the implant using the image intensifier, both from an AP perspective as well as laterally.

Note: This step is done without distraction so as not to damage tissues, longitudinal ligaments and nerve roots.

Note: Do not attempt to force and lock the polyethyl-ene inlay if the end plates have not separated. Additional discectomy and remobilization may be required if the end plates do not separate.

Note: The ProDisc-L implants are not designed to be used with bone cement.


7. Insert the PE-inlay


SFW874R Prodisc-L Distractor for height 10 mm



SFW577R Prodisc-L Inserter for PE-Inlay size M

SFW578R Prodisc-L Inserter for PE-Inlay size L

Lay the PE-Inlay as shown on the instrument (“dome up”) in the slot of the inserter. Use the disctractor corre-sponding to the selected implant height and attach it to the inserter.

Use the wing nut to screw the distractor down to the mechanical stop. While distracting the segment the PE-Inlay is automatically brought into position along the slot.

Check the distance between the implant plates using the image intensifier. There should be a visible radiolucent space between the metal plates.

Using the inserter, insert the PE-Inlay into the bottom plate of the implant until it snaps into place.

Note: It is crucial to check visually and manually if the PE-inlay is securely locked into the inferior im-plant plate (“no step, no gap”).

Check the final position of the prosthesis using the im-age intensifier.

Surgical Technique


8. Remove instruments



SFW582R Prodisc-L Lever for Insertion Instruments

Unlock the inferior plate by turning the arms outwards. Using a slide hammer, pull the inserter straight back and remove from the operative field.

Note: The use of a lever for insertion instruments can facilitate the rotation of the distractor arms.

The implant is now – oriented on the midline – securely seated on the cortical ring of the vertebral body.

Check the final position of the implant using the im-age intensifier, both from an AP perspective as well as laterally.


Multisegmental procedures

Perform multisegmental operations one segment at a time.

All instruments must be removed from the treated seg-ment before the next affected segment can be exposed and cleaned out.

Follow steps 2–8 as described above.

Note: In the case of multisegmental surgery, always start with the segment that is most severely col-lapsed.
